QwtEventPattern::QwtEventPattern()
       Constructor

       Seealso:MousePatternCode, KeyPatternCode

       A collection of event patterns.

       QwtEventPattern introduces an level of indirection for mouse and keyboard inputs. Those are represented
       by symbolic names, so the application code can be configured by individual mappings.

   enumQwtEventPattern::MousePatternCode
       Symbolic  mouse  input  codes.  QwtEventPattern  implements 3 different settings for mice with 1, 2, or 3
       buttons that can be activated using initMousePattern(). The default setting is for 3 button mice.

       Individual settings can be configured using setMousePattern().

       MouseSelect2
              The default setting for 1, 2 and 3 button mice is:

       • Qt::LeftButton + Qt::ControlModifier

       Parameters:numButtons Number of mouse buttons ( <= 3 )

       Seealso:MousePatternCodeboolQwtEventPattern::keyMatch(KeyPatternCodecode,constQKeyEvent*event)const
       Compare a key event with an event pattern. A key event matches the pattern when both have  the  same  key
       value and in the state value the same key flags (Qt::KeyButtonMask) are set.

       Parameters:code Index of the event pattern
           event Key event

       Returns:
           true if matches

       Seealso:mouseMatch()boolQwtEventPattern::keyMatch(constKeyPattern&pattern,constQKeyEvent*event)const[protected],[virtual]
       Compare a key event with an event pattern. A key event matches the pattern when both have  the  same  key
       value and in the state value the same key flags (Qt::KeyButtonMask) are set.

       Parameters:pattern Key event pattern
           event Key event

       Returns:
           true if matches

   QVector<QwtEventPattern::KeyPattern>&QwtEventPattern::keyPattern()Returns:
           Key pattern

   boolQwtEventPattern::mouseMatch(MousePatternCodecode,constQMouseEvent*event)const
       Compare  a  mouse  event with an event pattern. A mouse event matches the pattern when both have the same
       button value and in the state value the same key flags(Qt::KeyButtonMask) are set.

       Parameters:code Index of the event pattern
           event Mouse event

       Returns:
